Hello All,

I have been struggling with quite a few GPU WU failures over the past weeks and am not sure what they are. There are a number of failure scenarios, but one common one is included below.

I run a Q9550 quad core on a EVGA 790i Ultra mobo with 2x GTX 260 Core 216's with some overclocking applied. I have been successful for quite a while with the overclock... running around 650 Mhz and linked with Shader. What also hasn't worked for a while is the EVGA GPU Voltage Tuner..which they broke with the 182 series drivers and up. I have used it to help stabilize the card and GPU WU's in the past while it was working. I am currently running a 185.68 driver. Any thoughts on what I can do or check would be appreciated.

The C: drive file mentioned below is NOT on my hard drive so must have been compiled in with the GPU WU or Nvidia driver??

Thanks.

Thanks ET. I have backed off to 181.22 driver and started GPU voltage tuner and bumped up the default voltage about 50 mv. I am waiting for GPU WU's to download and I'll track my progress and report back.

What I am still interested in is what the heck is the c:\cygwin\home\speechserver\gpumd2\src\pme\CPME_cufft.cu? part of the message.

Anyway, i'd be interested to hear why they use cygwin/gcc instead of VS to compile the app...

I've backed off to a 181.xx driver and EVGA GPU Voltage Tuner works. I've tweaked the voltage up a little and things are looking promising. The last 5 or so work units completed successfully between my 2 GTX 260's.... I'll report again by the weekend. Looks like it was probably a GPU voltage issue.

I've been very successful since backing off to 181.xx drivers and running EVGA voltage tuner. As MarkJ suggest above, I got these same errors before I downgraded my driver and upped by GPU card voltage slightly (about 50 mv). Now I'm running very well on that box. Mark, you might try an experiment and try the same thing.

I'll check card temperatures next time (2xGTX 260 Core 216 Superclocked running at around 665 Mhz), but they typically run in the high 60's to high 70's depending on temperature in the room which can vary quite a bit. I have the fans set on auto using Precision 1.7.1.
